Environment-friendly plastic package bag

Abstract

The invention discloses an environment-friendly plastic package bag. The package bag is prepared from, by weight, 40-65 parts of polyolefin plastic, 35-45 parts of corn straw fiber, 5-8 parts of chitosan, 3.5-4.5 parts of methylisothiazolinone, 2-3 parts of bamboo charcoal micro mist, 4-6 parts of methyl phenyl polyborosiloxane, 2.0-2.5 parts of polysebacic polyanhydride, 5.5-7.5 parts of N-phenylmaleimide, 5-7 parts of hexamethoxy methyl melamine resin, 8-10 parts of diethyl malonate, 6-8 parts of decabromodiphenyl ether, 6-8 parts of dibasic lead phosphite, 0.1-0.2 part of coupling agent of organic titanate, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of laurinol sulfate, 4-6 parts of plant saponin, 0.1-0.2 part of polyamide wax micro mist and 1-3 parts of antibacterial agent. The package bag has good strength and toughness and is good in optical performance and easy to oxidize and degrade.

Description

technical field [0001] The invention belongs to the field of plastic products, in particular to a plastic packaging bag. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life, and is widely used in daily life and industrial production. [0003] Plastic packaging bags are consumables in daily life, and a large amount of plastic packaging bags are consumed every year. While plastic packaging bags provide convenience, due to excessive use and inadequate recycling, they also cause serious waste of energy resources and environmental pollution. In particular, ultra-thin plastic packaging bags are easily damaged, and most of them are discarded at will, becoming the main source of "white pollution". More and more countries and regions have restricted the production, sale and use of plastic packaging bags. In order to implement the scientific outlook on development and build a reso...

Problems solved by technology

[0004] At present, although there are various degradable plastic packaging bags on the market, tests have shown that most degradable plastic packaging bags generally begin to become thinner, lose weight, and lose strength after being exposed to the environment for 3 months, and gradually break into pieces. If these fragments are buried in garbage or soil, the degradation effect is not obvious

In addition, some additives in degradable plastics will change some characteristics of plastics, such as increased air permeability and moisture permeability, poor tensile strength, etc., which is not conducive to the promotion and application of degradable plastic packaging bags
